SPECIFICATION forming part of Letters' Patent No. 262,013, dated August 1, 1882. Application filed April 29, 1882. (No model.)

To all whom it 'may concern:

Be it known that we, LEON DEBARNOT and JULES JACQUOT, of Buenos Ayres, Argentine Republic, have invented Improvements in Locomotives; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed sheets of drawings, making a part of the same.

Our invention relates to improvements in locomotives; and it consists chieiiy in arrang-V iner the stokers platform over the connection between the engine and tender in a peculiar manner in engines having the axles of the wheels at a level above the boiler. This arrangement admits of the speed of' the pistons and other organs of the engine for a given speed of .the locomotive being much reducedl on account of the increase in diameter which may be given to the wheels, their axles being placed at the upper part of the locomotive. By leaving to the pistons the speed at present used a far more considerable speed may be imparted to the locomotive.

The arrangement of a locomotiveconstructed according to our invention may obviously be varied according to the use for which it is'designed. However, in order that our invention may be more clearly understood,we have shown in the annexed drawings a specimen of locomotive constructed according to our said invention.

Figure l shows an elevation of the locomotive. Fig. 2 shows a top View ofthe same.

Like letters of reference indicate similar parts in both these figures. i i

a a are the locomotive-wheels, of which the wheels a only are driving-wheels. b is the shell of the boiler, which is suspended from the axles by means of springs c and suitable axle-boxes. d is the re-box; c, the frame of the locomotive; and f, a hand-rail, allowing the engine-driver to walkround the locomotive in order to survey and lubrcate the several partsvof the same. g is the tender, the front part of which only is shown in the drawings. The arrangement of this tender as regards the water and coal supply may be varied as required, and its front part, together with the rear part of the locomotive, constitute thekplatform upon which stand the driver and sto er.

The total length ot' the engine and tender being considerable, we unite these parts byV means ot' extension-plates h, pivoted on a bolt, i'. This arrangement forms a pivoted joint, around which the engine and tender may turn when the train is running on a curved track.

The arrangement of the several parts of the mechanism, which are similar to those commonly used, may be' clearly understood by ret'- erence to the drawings.

k are the cylinders; l, the piston-rods, connected with the cranks m of the driving-axle. n are the slide-valves; o, the eccentric-rods actuating the same. p are the steamsupplying pipes for the slide-valves; q, a communication between the two steam-chambers of the boiler. r are the safety-valves, and s the steam-whistle. tis the link-motion; u, the actuatinglever, and v the transmission-levers, for the same. w are the suction and exhaust pipes for the feed-water. w are the feed-pumps, driven by rods y, pivoted on a cross-bar, z, which connects the piston-rods together.

The action of the above-mentioned parts does not require any special description, as it is the same as commonly used. However, we do not limit ourselves to the precise details herein shown and described, as the arrauge- 8o ment of the several parts of the engine may be varied to suit the different purposes to which the said engine is to be applied without in any way changing the nature of our invention. For instance, the number of the driving-axles may be varied, as well as the form and size of I the boiler and of the several parts of the mechanism.

We claim- In a locomotive having the boiler and the body ofthe tender hung below the wheel-axles, the pivot-joint connecting the engine and tend er, consisting of the two pairs of rigid plates h, which form the stokers oor or platform, meshing together in horizontal planes and held together by the vertical pin z', as shown and described.
